摩擦摩耗となると言われている。その先行技術としては
前記特公昭39−16950公報である。[Operation] When it is dispersed in PTFE, the metallic lead powder has an effect of transferring PTFE to the mating material (generally steel or stainless steel) of the sliding member. It is said that this results in low friction wear. The prior art is Japanese Patent Publication No. 39-16950.

見い出し本発明を完成させたのである。これは前記に述

に行われた結果である。However, in the present invention, commercially available metallic lead powder is classified (divided into grades), and various combinations are performed, and the average particle size has a weight-to-surface area ratio of 500 cm 2 / g.
The present invention has been completed by finding out by trial and error that the difference is 5,000 cm 2 / g, which is about 5,000 cm 2 / g, which is about 10 times different, and that it has extremely low friction and low wear. This is a result of the more detailed and efficient effect of the above-mentioned PTFE transfer.
比表面積を1,000〜8,500cm2/gとしたのは、1,000cm2/g
未満では摩擦摩耗において従来と変わらず、8,500cm2/g
を越えるものは工業的に金属粉末の製造が困難であるた
めである。The specific surface area of 1,000 to 8,500 cm 2 / g is 1,000 cm 2 / g
If less than 8,8500 cm 2 / g
This is because it is difficult to industrially produce metal powders that exceed the range.

量％未満では必要な摩擦摩耗特性を確保することはでき
ない。よって５〜30容量％とした。金属鉛粉はガスアト
マイズ、水アトマイズ、搗砕法によって製造される。If the added amount exceeds 30% by volume, it is difficult to maintain the improvement of the wear resistance property due to the brittleness of the material. Further, if it is less than 5% by volume, the necessary friction and wear characteristics cannot be secured. Therefore, it is set to 5 to 30% by volume. The metallic lead powder is produced by gas atomization, water atomization, and a crushing method.

くてはならない。Furthermore, at least one selected from the group consisting of metal oxides, metal fluorides and graphite, solid lubricants such as MoS 2 , WS 2 and PbS, fiber materials such as carbon fibers, and ceramics such as SiC should be added. This improves the friction and wear characteristics. However, if at least one selected from those groups is less than 0.5% by volume, the effect due to the addition with respect to the friction and wear characteristics does not take effect, and it is meaningless to add. If at least one of the above is added in an amount of more than 30% by volume, it becomes brittle and becomes unsuitable for practical use. Therefore, at least one of the above must be in the range of 0.5 to 30% by volume.

擦摩耗テストを実施したところ、本発明品より摩砕摩耗
特性は劣る。The large metallic lead in the surface layer has air permeability and tends to be oxidized even in the composition containing PTFE as a main component because the PTFE is made up of small particles during the baking step of PTFE. Therefore, when a frictional wear test was carried out by filling completely oxidized lead oxide, the abrasion wear characteristics were inferior to those of the product of the present invention.
